script_tag(name:"insight", value:"The flaw exists as PostgreSQL runs under a
non-root operating system account, and database superusers have effective ability
to run arbitrary code under that system account. PostgreSQL provides a script for
starting the database server during system boot. Packages of PostgreSQL for many
operating systems provide their own, packager-authored startup implementations.
Several implementations use a log file name that the database superuser can
replace with a symbolic link. As root, they open(), chmod() and/or chown() this
log file name. This often suffices for the database superuser to escalate to root
privileges when root starts the server.");
